The electron and proton of an atom are separated by \( 8.5 \times 10^{-10} \mathrm{~m} \) . Find the ratio between the electric force and the gravitational force between the two particles. [Electron charge \( =-1.6 \times \) \( 10^{-19} \mathrm{C} \) , Electron mass \( =9.11 \times 10^{-31} \mathrm{~kg} \) , Proton mass \( =1.67 \times 10^{-27} \mathrm{~kg} \) , Gravitational Constant \( \mathrm{G}=6.67 \times 10^{-11} \mathrm{Nm}^{2} \mathrm{~kg}^{-2} \) ]

A \( 1.15 \times 10^{45} \)

B \( 5.54 \times 10^{-29} \)

C \( 2.27 \times 10^{39} \)

D \( 8.04 \times 10^{-39} \)

Correct Answer: Option C
